At the time of American independence, Algiers was a nominal vassal of the Ottoman Empire with the power to conduct its own independent foreign relations. Algeria recognized the United States in 1795, although permanent diplomatic relations were not established until after Algeria emerged from subsequent French rule in 1962.Modern Flag of Algeria
Algiers recognized the United States by the signing of a peace treaty on September 5, 1795.
Algerian self-rule ended with French conquest in 1830. In 1848, the French government formally incorporated coastal Algeria into France as the departments of Algiers, Oran, and Constantine.
The United States recognized Algeria on July 3, 1962, when President John Kennedy issued a congratulatory message to the Algerian people upon their independence from France.

Formal U.S. Consular representation began with Joel Barlow’s presentation of his credentials as consul to Dey Hassan of Algiers on March 4, 1796. Prior to Barlow, John Paul Jones had been appointed as consul on June 2, 1792, but died before reaching post. Pierre Eric Skjöldebrand, brother of the Swedish Consul at Algiers, worked as an intermediary for the United States in negotiating a peace treaty with Algiers. Consular presence was interrupted from July 25, 1812 until July of 1815 owing to the Algerian War, one of the Barbary Wars. When appointee David Porter heard of the French occupation of Algiers in 1830, he chose not to take up his post, instead waiting for a new assignement as Chargé d’Affaires at Instanbul, where he arrived in 1831. There is no extant consul until the arrival of George F. Brown in 1835, whose exequatur was revoked in 1838. The United States also maintained consulates at the following posts:
Diplomatic relations and the American Embassy at Algiers were established on September 29, 1962, when Algerian agreed to the elevation of the American Consulate General to Embassy status, with William J. Porter as Chargé d'Affaires ad interim.
